Description

Hidden frame glass curtain wall system with aluminum alloy framework

Technical Field

The utility model relates to the technical field of architectural decoration, in particular to an aluminum alloy framework hidden frame glass curtain wall system.

Background

In the prior art, the traditional hidden frame glass curtain wall has the following main technical characteristics: (1) the glass is bonded on the aluminum alloy auxiliary frame by using silicone structural sealant, and in most cases, a metal connecting piece is not added. Therefore, the aluminum alloy subframe is completely hidden behind the glass, and a large-area full-glass mirror surface is formed. In some projects, vertical glass curtain walls employ hidden framing curtain walls with metal connectors. The glass and the aluminum alloy auxiliary frame are completely bonded by structural adhesive. The structural adhesive is required to bear the dead weight of glass, the wind load and the earthquake action borne by the glass, and the hidden frame glass curtain wall is influenced by temperature change, so that the structural adhesive is a key link of the safety of the hidden frame glass curtain wall. (2) The aluminum alloy upright post is connected with the main structure by two steel structure adapter pieces generally. During connection, the aluminum alloy upright posts are arranged between the two steel structure adapter pieces and are fixedly connected through bolts. (3) The aluminum alloy beam and the aluminum alloy column are usually connected by adopting an aluminum alloy corner connector. The aluminum alloy corner connectors and the upright columns are connected through stainless steel bolts, and the aluminum alloy corner connectors and the aluminum alloy cross beams are connected and fixed through self-tapping screws.

Thus, the above conventional techniques have several major drawbacks: (1) after the steel structure adapter is connected with the aluminum alloy stand column and fixed, the bolt and the steel structure adapter are exposed outside the aluminum alloy stand column, and the appearance effect of the bolt and the steel structure adapter is influenced. (2) The aluminum alloy stand column and the aluminum alloy cross beam are connected by the aluminum alloy corner connectors, the overall stability after the connection is poor, and particularly when the aluminum alloy cross beam and the aluminum alloy corner connectors are connected by self-tapping screws, the installation precision is poor, the disassembly and the assembly are inconvenient, and the firmness and the durability are not ideal. (3) Because the structural adhesive is required to bear the dead weight of the glass, the wind load and the earthquake action borne by the glass and the influence of temperature change, the potential safety hazard of the hidden-frame curtain wall in the practical engineering application is increased. And the structure glue injection of the hidden frame curtain wall needs to be carried out in a specific environment, the compatibility test needs to be carried out on the structure glue and all materials for bonding the structure glue, and the glue injection quality and the processing precision are higher. Accordingly, the construction cost is relatively increased, and the construction process becomes complicated.
